70mm Jet Water Thruster with 6mm Stainless  Shaft Couplings 8X6mm For Boat Surfboard Rc Model Boat

100% Brand New

This 70mm v2 black water jet is much better than V1 grey .

Inner Shaft Diameter is 6mm

Water jet shaft is 316 stainless steel.

There are two high speed stainless steel bearings(40000rpm)

Coupling size is 6mm to 8mm.

Pitch ratio of the impeller is about 1.0.

The jet's gasket is a bearing(stainless steel).

The grey v1 water jet max thrust ≥25kg/250N. (alum impeller,12s lipo, 56123 230KV motor, 300 to 400A ESC)

The black v2 water jet max thrust ≥35kg/350N.(alum impeller,12s lipo, 56123 230KV motor, 300 to 400A ESC)

recommended 8000 to 10000rpm. CNC aluminum impeller works much better than the plastic impeller.

If you use 6S lipo battery and 56104 360kv motor, you can get the thrust of 16kg

It is ok for 56104/56114/56123 inner rotor motor. or other outer rotor motor which installling distance is 30mm/40mm/44mm and it is M4 screw.

If your battery is 6s, you could choose 56104  Kv360, if your battery is 8s/10S/12S, please use lower kv, thank you. For 12S lipo battery, 56123 230KV is good.   ESC 180A to 400A is good.

The surface is not super perfect due to the 3D print limits, but we will make it as good as possible.

Tips: if you need other size coupling(56123 motor shaft is 10mm) or other needs(like color, different direction), you coud leave us a message when you order it.
